I went to the hospital recently because i had complications in my testicles, so they put a iv in me and i passed out but when i woke they where finished. when i was in there my arm felt cold all the way until i left(i took it as the iv). so it is 2 weeks later and its not bothering me foreal but when i stretch or bend my arm it hurts like, when you have swelling and bruised a area and its tender, but its been two weeks since this occured. and it only seems like this when i am laying down, can you explain to me what this is, i have had an iv once before but i cant remember which arm it was is and, but ik that for two weeks i dont know if its supposed to be sore like this and still feel cold around where i had gotten it placed, swollen i dont know because i have been playing basketball the past 2 days but this has been ongoing since i left......im hoping nothing serious is happening or they shot my veins..........
